Raws li peb cov kev sib tham yav dhau los ntawm kev txheeb xyuas cov khoom siv thiab xaiv rau 304/316 stainless hlau bolts siv hauv cov tshuab kub khiav, cov hauv qab no tuaj yeem siv los txiav txim siab yog tias kub khiav stainless hlau bolts tau dhau los kho cov kev kho mob:
Cov tsos mob Hardness Test: Kev daws teeb meem- kho stainless hlau bolts muaj qis hardness. Maj mam khawb qhov saum npoo nrog cov ntaub ntawv txheem yuav ua rau ntiav ntiav, ntau qhov sib txawv ntawm cov ntsia hlau kho, thaum cov ntsia hlau tsis kho yuav muaj zog dua.
Metallographic Observation: Metallographic tsom xam ntawm cov qauv yuav qhia ib tug uniform austenitic qauv nrog tsawg carbide nag lossis daus tom qab kev daws teeb meem, thaum untreated bolts yuav qhia pom tseeb carbide aggregation ntawm grain ciam teb.
Corrosion Resistance Test: Immersing the bolts in a specialized test solution will show the strong corrosion resistance in solution-kho bolts, tsis muaj qhov pom ntawm xeb tshwm sai sai. Cov bolts tsis kho yuav corrode thiab discolor sai heev.
Kev Tshawb Fawb Txog Kev Tshawb Fawb: Tshawb xyuas tus neeg muag khoom cov ntaub ntawv tshaj tawm. Kev daws teeb meem- cov khoom kho yuav qhia meej txog cov txheej txheem kev daws teeb meem, thaum cov ntsia hlau tsis kho yuav tsis muaj cov ntaub ntawv txheej txheem.
Kev Tshawb Fawb Txog Kev Tshawb Fawb: Cov txheej txheem saum toj no tuaj yeem txiav txim siab seb cov bolts tau dhau los kho cov kev daws teeb meem, kom ntseeg tau tias qhov kub siab ua haujlwm ntawm cov bolts kub.
